PURPOSE:To obtain a unique toy which moves synchronously with a specific musical instrument in music by demodulating musical performance information, exchanging it for pseudo operating information, and executing a musical performance operation in accordance therewith. CONSTITUTION:In order to distribute musical performance information of each musical instrument to each channel of an MIDI signal, and to express these tone colors by one channel, musical interval data called a note number is allocated to tone colors of these drums one by one. The MIDI signal whose waveform is shaped by an MIDI signal receiving circuit 2 is supplied to an MIDI decoder 3, and the MIDI decoder 3 fetches note/ON and note/OFF signals of a rhythm channel contained in the MIDI signal, exchanges its note information by an exchange means 4, and outputs an ON/OFF signal to a driving means 5. The driving means 5 controls the left and right hands and feet of a doll seated on a drum set, respectively in accordance with the ON/OFF signal. |
